Background technology
Body mount is meant the nonrigid connector between separate frame construction and the vehicle frame, is generally made by rubber, and vehicle frame supports separate frame construction by body mount, to alleviate body vibrations, improves vehicle ride comfort.By the body mount system is carried out force analysis as can be known, the load of vertical direction is the principal element that influences the body mount anti-vibration performance.In the Automobile Design process,, need test at the stressing conditions of vertical direction the body mount support for the load that makes body mount and vertical direction is complementary.
Conventional test methodologies generally with simple foil gauge as force cell, test procedure is as follows:
1) selects test point at body mount support place, use sand papering, paste foil gauge.
2) be connected with data acquisition system (DAS) with the foil gauge sealing that pastes, and by wire harness.
3) on test point, progressively load standard test weight, test strain numerical value under the different loading environments by data acquisition system (DAS).
4) according to load mass and corresponding strain data, demarcate the value of exerting oneself-strain curve.
5) vehicle body and body mount are installed on the vehicle frame, middle thru-bolt is tightened, and tests strain numerical value by data acquisition system (DAS), and calculates body mount support force this moment according to demarcating good power value-strain curve.
The shortcoming that this method of testing exists mainly contains the following aspects:
1) foil gauge is pasted in reconnaissance on the body mount support, need finish by experienced slip-stick artist, usually select stress to concentrate and the symmetrical point in position, chosen position is improper may cause demarcating power value-strain curve the time, and strain numerical value is too little, the calibration curve distortion, its operation easier is bigger, to having relatively high expectations of tester.
2) polishing vehicle body mounting bracket process can produce dust, the contaminated environment and the health that is harmful to health.
When 3) demarcating power value-strain curve, need load counterweight at body mount support place, because body mount backing positions contact area is little, loading procedure is very dangerous, exists counterweight to drop, injure by a crashing object potential safety hazards such as personnel.
4) most of SUV vehicles adopt 12 body mount arrangements, and each body mount support place all needs reconnaissance, pastes foil gauge, demarcation, test and calculating.Repeat work, waste time and energy, inefficiency, the test period is long.
5) 4 foil gauges need be pasted by each body mount support place, and calculating according to 12 body mounts needs 48 foil gauges, and foil gauge can not reuse, and cause certain waste of material.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of easy to operate, safety is provided, the high and reusable body of a motor car mounting bracket force sensor of efficiency of measurement and precision.
Problem described in the utility model realizes with following technical proposals:
A kind of body of a motor car mounting bracket force sensor, comprise in the formation that the ring-shaped base that keeps flat, diameter are less than the internal diameter of ring-shaped base and bearing column, semi-girder and the foil gauge coaxial with ring-shaped base, the upper end of described bearing column is higher than the end face of ring-shaped base, the lower end is higher than the bottom surface of ring-shaped base and is connected with ring-shaped base by semi-girder, and bearing column is provided with the bolt hole of coaxial with it and up/down perforation; Described foil gauge is pasted on the semi-girder, and its signal output part connects data acquisition system (DAS).
Above-mentioned body of a motor car mounting bracket force sensor, described semi-girder is provided with four, they are rectangle around even distribution of the axis of bearing column and xsect, the upper surface of wherein non-conterminous two semi-girders is pasted with foil gauge, the lower surface of two other semi-girder is pasted with foil gauge, the lead-in wire of four foil gauges on four semi-girders is in turn connected into ring-type, and non-conterminous two contacts connect driving voltage, and the output signal between two other contact connects data acquisition system (DAS).
Above-mentioned body of a motor car mounting bracket force sensor is provided with cable hole between the inwall of described ring-shaped base and the outer wall.
The utility model is installed between body mount and the body mount support, vehicle body gravity acts on the vehicle frame through body mount, bearing column, semi-girder and annular base successively, data acquisition system (DAS) is during according to the stressed generation of semi-girder distortion, and foil gauge changes in resistance amount just can calculate force value.The foil gauge of this sensor is pasted on the semi-girder, after demarcating, can reuse, not only avoided the waste of material, and test the time need not be pasted foil gauge and the power of demarcation value-strain curve again, greatly reduce operation easier, get rid of potential safety hazard, improved measuring accuracy and work efficiency.
